[pve-devel] [PATCH manager 1/2] ui: storage: oci registry pull: fix reference parsing

[Filip Schauer]

Fixes an issue where pasting an OCI image reference with a additional
prefix (for example docker://registry.fedoraproject.org/fedora:latest)
into the reference field caused the tag parser to split the string
incorrectly. With this patch the tag is only moved when a valid OCI
reference is entered.
